Dears,
We have 6 Expressway servers installed between HO & DR as follows:
HO
Expressway C Primary
Expressway C Failover
Expressway E Primary
Expressway E Failover
DR
Expressway C
Expressway E
As far as I understood:
- HO Expressway C Primary & HO Expressway C Failover are considered as 1 cluster.
- HO Expressway E Primary & HO Expressway Failover are considered as 1 cluster.
- DR Expressway C is considered as 1 server.
- DR Expressway E is considered as 1 server.
I know that I need to upgrade the primary node in a cluster first followed by the second node. But could you please advise if I shall start with the C or E servers?
And has anyone gone through a similar upgrade and has recommendations?
Thank you,
Lara
